funciona muy bien lo uso para mi iglesia, pero rompí por accidente la antena ¿hay refacción?

Let's start with the item. Build quality looks and feels very solid. Instructions are clear and easy to understand. Simple to change between 1W and 7W settings, very simple to set transmit frequency. Sound quality is very good for the money, and in true stereo. I bought this to transmit music streamed from my PC around my house and out to the barn, and it does so very well. 1W easily covers my home and halfway down the block....which leads us to what needs to be discussed.The item has a legitimate FCC Part 15 number on it....but this item will EASILY violate part 15 on the 7 Watt setting. On a clear channel using the 7W setting, it will get out well over a mile. Put it up high outdoors, and the range doubles. The last thing you want to do is attract the ire of the FCC....but that only happens if someone complains. It behooves the user to ensure that nobody complains. Use the low power setting when possible. Ensure that you aren't accidentally trampling on a licensed broadcast. Do not broadcast anything that could be deemed offensive or vulgar. And shut it down when not in use. Be smart, and everything will be OK. So why does the manufacturer sell an item that can be used illegally? Well, every car manufacturer sells vehicles that will easily exceed legal speed limits. The onus for prudent use falls upon the consumer. FCC fines can be massive, so use common sense. If you live in a rural area with few neighbors, you can probably use the 7W setting with no problems. In an urban area, that's probably not a good idea.So there you have it. Fun little piece of equipment at a great price. Use it wisely, and enjoy.

7ery well made and powerful. In high power mode it needs to be at a good distance from other electronics. With it near 2 different tv's the off air signal was completely lost while the device was on. Haven't tested around blue tooth and not sure how it effects wi-fi. Within a few inches of a volt meter measuring indoor solar panel the volt meter picked it up and read about a volt more! Not sure if the signal went through the panel or the analog volt meter picked it up directly. But it should do well for the purpose it is sold for. I'm quite happy with it.

I had ground loop problem when I connected this to the headphone output on my sound system. This caused an annoying 60HZ buzz in the sound. I got an isolater for the audio input and now it sounds really good! I bought the BESIGN Ground Loop Noise Isolator here on Amazon.I use it to transmit to all the FM recievers in my house and garage and play music from the computer. So nice to have music in every room.
